Common printing ways of seals include laser printing, hot stamping, silk screen, etc.
Advantages of laser printing
(1)Permanence: printing will not fade out due to time and environment and printing effect is difficult to imitate and change with stronger anti-fake function, therefore, laser printing way has obvious advantages at automobile industry field which has strict requirements of traceability.
(2)Printing effect is very fine: the diameter of facula after focus can reach 0.04mm minimum or less, therefore, effect is very fine. 
(3)Operation cost is low: although purchase investment of laser equipment is larger than traditional equipment, laser printing is rapid in speed, small in energy and easy to automatic management; it does not need general consumable items. As long as laser equipment can normally work, long-time continuous operation can realize. It has large advantages at cost and technical effect comparing with traditional printing ways.
(4)Non-contact processing: the energy carrier of laser printing is light beam with same wave length. Beam radiates on the surface of seals, there is no mechanical stress, and there is no influence on mechanical features and no chemical pollution or noise.
(5)Strong adjustability: print at most metal or non-metal materials, therefore adopt computer intelligent control, laser equipment can rapidly adjust printing contents including barcode, QR code, etc. through software.
Disadvantages of laser printing:
Single color. Raw materials need to add laser powder.

Advantages of hot stamping:
(1)Wide selection range of hot stamping foil, such as different colors, different color effects, and different applicable materials.
(2)Vertical hot stamping. Adopt computer digital control carving version way to formulate vertical hot stamping version to make the picture vertical. To make relief effect at surface and appear strong visual impact effect. Vertical hot stamping has special touch feeling. (3)Good quality, high precision, clear and sharp picture edge.
(4)High surface glossiness, and bright and smooth picture.
Disadvantages: hot stamping technology requires to adopt special equipment and needs heating device and making hot stamping version, therefore, higher cost.

silk screen
Advantages of silk screen
(1)Without limit of object size and shape. General printing can only be at surface, while silk screen can not only print on surface, but also on special shapes, like ball. As long as with shape, silk screen can be adopted.
(2)Layout is soft and pressure is small and silk is soft and elastic.
(3)Silk level has strong coverage and can make white printing at black paper with strong third dimension.
(4)Apply to various printing inks.
(5)Strong resistance to rotation performance can make color unchanged. When printing adhesive stickers, additional film is not needed.
(6)Flexible printing ways
(7)Convenient to make plate, low cost, easy to master technology
(8)Strong adhesive force
(1)Printing speed is lower than other ways;
(2)Thick printing lines and unable to print fine pictures.
(3)Printing levels are not good. Highlight part is not easy to print and dark part is easy to get mixed.
(4)Low pressrun of screen printing plate.
